DP83822I: Must the NC pins be left floating?

Part Number: DP83822I
Other Parts Discussed in Thread: TLK105

Dear support team
I have a question about the DP83822I regarding the NC pins. 

During the chip crisis the DP83822I was not availabe and that's the reason why we have extended our design, so that it was also possible to populate the TLK105 instead of the DP83822I:

Now we have realized that we forgot to remove the yello marked components when we switched back from the TLK105 to the original part DP83822I. IN the DS of the DP83822I  it is recommended that the NC pins are not connected. 
Question: Are these external components a risk to run into an issue? SHould we remove them or is this not a problem if they are there?
Best regards
